🦴 Caltrate: calcium brand history — from Lederle 1984 to Haleon
How a specialized calcium and vitamin D brand became one of the most trusted in the world
Caltrate is a specialized brand of calcium supplements, often with vitamin D, focused on bone and teeth health. The brand was launched in 1984 and is now owned by Haleon.
History: launch in 1984
The Caltrate brand was launched in 1984 by the Lederle division of American Cyanamid in the US. The first product was Caltrate 600 — a 600 mg calcium carbonate tablet.
Calcium was becoming a "fashionable" micronutrient at the time, and Lederle saw an opportunity to create a specialized product for bone health, distinct from general multivitamins.

Calcium and bone health
Calcium is a key mineral for bone and teeth health. Adequate intake of calcium and vitamin D as part of a healthy diet may help reduce the risk of osteoporosis.
The brand emphasizes science: Caltrate is backed by more than 25 years of nutritional research and is formulated in line with US Institute of Medicine recommendations.
Formula: 600+D3
The main format is Caltrate 600+D3: 600 mg of calcium as calcium carbonate and vitamin D3 (cholecalciferol).
The Caltrate Plus line additionally contains 800 IU of vitamin D3, 20 mcg of vitamin K1, 50 mg of magnesium, 7.5 mg of zinc oxide, 1 mg of copper and 1.8 mg of manganese.
| Component | Caltrate 600+D3 | Caltrate Plus |
|---|---|---|
| Calcium | 600 mg (carbonate) | 600 mg (carbonate) |
| Vitamin D3 | High level | 800 IU |
| Vitamin K1 | — | 20 mcg |
| Magnesium | — | 50 mg |
| Zinc / Copper / Manganese | — | 7.5 mg / 1 mg / 1.8 mg |
Lines and forms
The Caltrate range includes several dosage forms.
| Line | Form | Purpose |
|---|---|---|
| Caltrate 600+D3 | Tablets | Calcium + vitamin D3 |
| Caltrate 600+D3 Soft Chews | Soft chews | For those who find swallowing hard |
| Caltrate 600+D3 Gummy Bites | Gummies | Convenient intake (based on calcium phosphate) |
| Caltrate Plus Minerals | Tablets / Chewables / Minis | Calcium + magnesium, zinc, K1, copper, manganese |
How it differs from multivitamins
| Aspect | Caltrate | Multivitamins (Centrum) |
|---|---|---|
| Focus | Calcium | Full complex |
| Specialization | Bones | General |
| Calcium dose | 600 mg (high) | ~200 mg (low) |
| Vitamin D | High D3 | Included |
The main difference is specialization in a high dose of calcium, focused on bone health, rather than a general vitamin complex. Caltrate does not replace a full multivitamin but solves a specific task.
Scale and price
Caltrate is one of the most recognizable specialized calcium brands in the world, positioning itself as the "#1 trusted calcium brand". The brand is especially strong in the Asia-Pacific region, including China, where sales grew at double-digit rates.
The price of Caltrate is average for specialized calcium supplements: more expensive than cheap alternatives, but affordable in pharmacies. The parent company Haleon has revenue of more than £11 billion (US$14 billion).

| Pros | Cons |

| Vitamin D3 for absorption | Calcium carbonate needs to be taken with food |
| Long history and science | Average price |
| Various forms (tablets, chews, gummies) | Not for everyone with kidney stones |
